Tests of John E. Fast and Company Capacitors
Abstract
The capacity and the d.c. leakage of the capacitors were measured as received. A flash test of 2-1/2 times rated voltage was applied for 15 seconds to the terminals of the capacitors and from terminals to case. The units were then immersed in salt water at 50 deg C and after 2 hours were transferred to a salt water bath at 0 deg C for 2 hours, after which they were left for 24 hours in a saturated solution of salt water at room temperature. After the capacitors were rinsed in fresh water and allowed to dry for one hour, the capacity, d.c. leakage, and flash tests were repeated. The capacitors tested satisfactory before being immersed in salt water, but all failed to withstand the salt water immersion test.
